UNITED STATES ,ATENT EDWARD WILBUR, or ALBION, NEW roux.

IMPROVEMENT IN STOVES Specification forming part of Letters Patent No. 42,893, dated May 24, 1864.

To aZZ whom it may concern.-

Be it known that I, EDWARD WILBUR, of the village of Albion, county of Orleans, in the State of New York, have invented a new and improved stove attachment, for the more immediate, rapid, and perfect radiation and use of the heat generated in the stove for the warming of rooms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

The nature of my invention consists in a combination of radiating-fines, so arranged and so shaped that the heat in circulating through them is rapidlyvand most thoroughly thrown out, affording a greater amount of heat for house-warmin g from a given amount of fuel than by any other known arrangement.

Vessels for holding liquids should have a shape combining the greatest capacity with the least outline-surface, and the circle unites these elements the most perfectly; but in fines for the radiation of heat the reverse rule should be observeda shape combining the least capacity with the greatest outlinesurface.

form in this respect but stove-pipes, and also many warming-stoves, are made cylindrical-the worst possible shape. This important error I have obviated in the shape of my radiating fines.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Any form or design of stove or tire-box may be used; but it should have no more capacity 1 or room than is necessary for the combustion l fines with the firebox.

of the fuel, it being but the laboratory for the production of heat by combustion, and as heat very rapidly becomes latent immediately after its production, it should be carried immediately and directly into the radiatingtlues, where it is rapidly thrown out into the room; and that the radiating-fines may have the largest amount of surface with the smallest amount of area, they are to be made broad and shallow, and of any convenient shape; and that the tines may not have external surfaces radiating against each other, they are to be connected at their an gles; and

A parallelogram of the least depth .with the greatest breadth is theniost perfect 1 l l l l l l l an ellipse; and the front of each flue should be the arc of a circle or of an ellipse, whose extremes should touch each other, the fronts of all the tines being of one sheet of iron bent into form, the backs being a shorter circle, and forming the chords by touching the extremes of the front arcs of the fines, as shown in the drawings Nos. 2, 4, 5, 7, and S. The broad ascending flue 0, Nos. 7 and 8, receives the heated air direct from the fire-box through the opening 0, and at the top thereof it branches oft each way through the connecting-passages e 0 into the descending lines I) b, at the bottom of which they enter the ascending fines a a through the short passages f f, and from thence, through the openings D D, it enters the smoke-chamber d and passes into the stove-pipe through the opening and collar G-the three'horizontal plates, Nos. 2, 4, and 6, to be made of cast-iron; the radiating-fines to be made of cast or sheet iron; the sides of the smoke-chamber to be of sheet or cast iron; the sides of the tirebox to be made of either cast or sheet iron of.

any form or pattern.

The double lines in the Drawings 2, 3, 4, 5, and 6 of the horizontal plates of cast-ir0n represent grooves for receiving and confining the edges of the perpendicular side sheets or plates.

The damper B is for opening a more direct connection with the pipe when occasion shall require a stronger draft, as in starting a fire.

I do not claim as my invention any particular form of tire-box or stove, nor any particular manner of connecting the radiating- Neither do, I claim as my invention any exact form or shape of the tines, as they may be fluted or plain, in the form of parallelograms, or triangles, or segments of circles, (as represented in the accompanying drawings,) or truncated segments of circles, or oval, or any other available shape. Neither do I claim as my invention any given mode of connecting the radiating-flues with the stove-pipe; but

What I do claim as my invention, and nothing more, is-

A compact series of large-surfaced, broad and shallow non-interradiating ascending and the back thereof being formed of sheet or and descending radiating-fines, connected at cast-iron, in one or more pieces, substantially the sides or angular edges, arranged conas shown and described.
